behaviour(establishing the ground of divorce) the ground of divorce, irretrievable breakdown, is established by this mode, in English and in Scots law, if the defender has at any time during the marriage behaved (whether or not as a result of mental abnormality and whether such behaviour has been active or passive) so that the pursuer cannot reasonably be expected to cohabit with the defender. Courts look at the whole circumstances and often seek a pattern of behaviour in which older incidents are highly relevant. A single incident, however, can constitute behaviour if it strikes at the heart of the marital bond.
BEHAVIOUR. In old English, haviour without the prefix be. It is the manner of having, holding, or keeping one's self or the carriage of one's self with respect to propriety, morals, and the requirements of law. Surety to be of - good behaviour is a larger requirement than surety to keep the peace. Dalton, c. 122; 4 Burn's J. 355.
